I got tired of the tires on my diesel pickup kicking up tar, rocks, and other debris onto the hull of my boat. So I built this for about $12.

I never bother putting anything over my tow rig ties when I'm hauling the Jeeps on the car trailer. But my boat is another matter.

A couple years ago I looked into buying a set of hitch-mounted mudflaps and was shocked at the $250-$350 price tag. I headed down to NAPA and bought some of their cheapest in-house mudflaps for about $10/pair. I had an old piece of fence post tubing, a short section of trailer hitch stock (too short to do anything else with) and some junk angle iron and square tube that was just sitting by the side of my shed. I welded it all up so it'd slide over the hitch and socked it down with a 1/2-inch bolt to keep it from wobbling. About $2 in mounting hardware later I had my mud flaps installed and now my boat hull is clean when I get to the river.
